IVITANIFOLDING DEVICE.

SPECIFICATION formingpart of Letters Patent No. 756,139, dated March 29,1904.

Application filed September 14, 1903. Serial No. 178,090. (No model.)

To all whom it may concern:

Be it known that I, JOHN H..PETROSKEY, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Manifolding Devices, of which thefollowing is a specification, reference being had to the accompanyingdrawings, which form a part of this specification.

My invention has for its object certain new .and useful improvements ina manifolding cylinder in position to insert the carbon-sheet or roller.Fig. 5 is a partial vertical longitudinal section through one end of thecylinder. Fig. 6 is a view in cross-section similar to Fig. 3 andshowing a carbon-sheet engaged with the cylinder. Fig. 7 is a view inrear elevation showing the cylinder mounted upon a base and illustratinga modification of the invention.

The aim of my present invention is to provide more especially in amanifold device a cylinder to hold the carbon sheet either mounted upona roller or separate from the roller, as may be preferred, theconstruction being such that the carbon-sheet or roller may be readilyengaged in place or adjusted or removed, as may be desired, so that thecarbon-sheet may be replaced readily and may be readily drawn forward,held in position, or detached, as circumstances may require.

I carry out my invention as follows: In the drawings, a representsanysuitable base. In Figs. 1 to 6 the base is shown formed with theintegral brackets or shoulders (indicated at b b) to support a cylinder0. In Figs.

1 to 6 said base is shown provided with clamping-arms, (indicated at dd,) whereby the base a may be engaged upon an additional support e-as,for example, the cover of a book or upon leaves of a book in which itmay be desired to make a carbon copy. Said additional support may beemployed to carry a block or plurality of sheets f, upon which carboncopies are to be made. In the form shown in Fig. 7 the brackets orshoulders b b are shown attached to any suitable supporting-base g bymeans, of clamping-ears, (indicated at h h.)

I would have it understood that I do not limit my invention to anyparticular construction of the base nor to any particular manner ofattaching the brackets or shoulders I) Z) to a base, as my inventioncontemplates any suitable base provided in any desired manner withbrackets or shoulders]; 6 to support a cylinder 0. The cylinder 0 has apivotal and eccentrical connection with said brackets, the cylinderbeing provided at a suitable point upon its periphery with pivotal arms,(indicated at z' 6,) by which the cylinder is eccentrically suspended ata suitable point upon the upper edge of said shoulders or brackets, theshoulders or bracketsbeing provided 'withorifices (indicated at toreceive said pivotal pins.

The shoulders I) b are constructed of sheet the cylinder has beenengaged in place to hold the cylinder from inadvertent disengagementtherefrom. The cylinder is formed with an opening (indicated at is) atthe front thereof,

the opening being preferably formed by the meeting edges of the metal ofwhich the cylinder is formed. The cylinder is also made of spring sheetmetal, so that'the edges forming the opening is may be closed togetherupon a carbon-sheet Z, drawn therethrough, closing said edges together,effectually binding the carbon-sheet in place when the cylinder is innormal position, so that the carbon-sheet is held from being displaced.The ends of the cylinder itself are open, but when in normal positionare closed by being swung downward inside the brackets or shoulders Z26, having its edges adjacent to the opening is closed to- Lin gether byspring-arms m m at the rear edge of the base, said arms being readilyformed by kerfing the rear edge of the base, as indicated ELI/7H1, asuitable distance, the rear edges of the spring-arms m 77?. beingpreferably turned downward slightly, as shown. The cylinder is somounted in its brackets that when it is swung down into normal positionit will press upon the spring-arms, the springarms thereby forcing theopen edges of the cylinder together to bind the carbon-sheettherebetween, as shown. In order to more readily accomplish this end andmake the edges of the cylinder spring together more readily, I prefer tokerf the cylinder on the rear side thereof, as indicated at p. The basea is preferably recessed between the springarms, as indicated at q, therecess assisting in forming the spring-arms already mentioned and alsopermitting the engagement of an elastic band r in said recess to aid inholding the base a upon any suitable support. The brackets b b are alsopreferably provided at their rear edges with stops 8 s to limit themovement of the cylinder when swung down into normal position. I preferalso to construct one edge of the cylinder adjacent to the opening itwith a projecting straight edge t to facilitate the tearing off of thecarbon when a portion of the same has become worn, the edge It forming acutting edge.

What I claim as my invention is 1 In a manifolding device a baseprovided with yielding brackets and a cylinder eccentrically mounted insaid brackets, said cylinder provided with a longitudinal opening, andmeans to close said opening when the cylinder is in normal position.

2. In a manifolding device a base provided with spring-metal brackets,and a spring-metal cylinder eccentrically mounted in said brackets, saidcylinder constructed with a longitudinal opening whereby the cylindermay be swung down therebetween into normal position and out of normalposition, and means to close said opening, when the cylinder is innormal position.

3. A manifolding device provided with brackets, a spring-metal cylinderprovided with a longitudinal opening having a pivotal eccentricengagement with the brackets, said cylinder constructed with open ends,the ends thereofbeing closed by the brackets when the cylinder is innormal position, and means to close said opening when the cylinder is innormal position.

4. In a manifolding device the combination of a base provided withbrackets and with spring-arms, a swinging cylinder eccentrically mountedin said brackets provided with a longitudinal opening, said cylindercontacted with the spring arms when in normal position whereby saidopening will be closed.

5. In a manifolding device a base provided with clamping-arms and withspring-arms and with brackets, a swinging cylinder eccentrically mountedin said brackets provided with a longitudinal opening, said cylindercontacting with the spring-arms when in normal position to close saidopening.

6. In a manifolding device a base provided with clamping-arms and withspring-arms and with brackets, a swinging cylinder eccentrically mountedin said brackets provided with a longitudinal opening, said cylindercontacting with the spring-arms when in normal position to close saidopening, said cylinder also provided with an elongated opening on therear side thereof and with a cutting edge.

7. In a manifolding device a base provided with clamping-arms and withspring-arms and with brackets, a spring-cylinder eccentrically mountedin said brackets provided with a longitudinal opening, said cylindercontacting with the spring-arms when in normal position to close saidopening, said base recessed on its rear edge between the spring-arms forthe purpose described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOHN H. PETROSKEY.
